Question 20

purposes of the pleura

Answer 20

lubrication (allows lung to move) and surface tension (keep lung inflated)

intercostal and musculophrenic

Question 25

blood supply of the visceral pleurae

Answer 25

bronchial arteries

Question 26

costodiaphragmatic recess

Answer 26

where the diaphragmatic pleura meets the costal pleura, common site of pleural effusion
